- AUTOMATIC BADIATOR-VALVEAND HUMIDIFIER.

To all whom it may concern:

Be it known that I, CLARENCE C. SHIPP, a citizen of the United States, residing'at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Automatic 7 Radiator-Valves and Humidifiers, of which,

thefollowing is a specification.

Many, if not all, of the automatic air valves, employed for releasing accumulated air in steam and hot water radiators, become lined to such an extent as to impair their efliciency, thereby allowing water to be ejected after the air has been completely exhausted.

The present invention relates to whereby accumulated air within steam and hot water radiators can be completely exhausted, besides eliminating the objectionable features heretofore referred to.

One cat the objects of the present invention consists in the provision of an air valve for exhausting air from steam and hot water radiators in which accumulated air in such radiators can be silently ex'- hausted.

A further object of the invention consists in the provision of an air valve whereby after the airhas been exhausted from the radiator acertain volume of water can be withdrawn from the radiator and dis charged into a water-receiving pan, the" water in the pan serving the purposes of sealing the end of the discharge pipe; con

trolling the action of the cut-off valve, and also serving as the medium for humidifyingthe air of theroom in which theradiator is situated.

A still further object of the invention consists in the provision of an air valve of the above character in which the valve is seated and unseated by the rising and falling of the water level within the waterreceiving pan. i

I accomplish the above and other objects and advantages of the invention, as will appear from a perusal of the specification and claims, by means of the construction I illustrated in the accompanying drawings,

forming a part hereof, in -which- Figure 1 is a central vertical section through the outer casing of the air valve and the water receiving pan, showing the remaining parts of the valve construction in elevation. Fig. .2 is a cross section of the device, on the line 2 2 in Fig. Fig. 3 is Specification of Letters Patent.

for overcoming avacuum which might 1 otherwise result when the supply of steam or hot water is cut oil. The present invention contemplates employing said aperture by inserting therein an elbow 18 having a check-valve 19 therein (see Fig. 4), Whose object will be hereinafter described. The elbow 18 is engaged by a suitable air and .water conductor pipe 20 of small dimensions, by means of a suitable coupling 21, which conveys air and water from the interior of the radiator and discharges same into a water receiving pan 22 which is ordinarily inserted into the intervening space 100 16 located in the coils of the radiator. The conductor pipe 20 is preferably composed a portion of its length of a number of convolutions 23, so that a circuitous passage- .way of sufiicient length is obtained for converting steam passing through pipe 20 into water. Pipe 20 connects by means of a coupling 26 with a T-shaped pipe 27 the latter communicating with the interior of the cut-01f mechanism so that the air and water discharged from the radiator are passed through a valve'and are thus subject to regulation in their movements before being finally discharged into the water receiving pan 22.

The mechanism for controlling the outflow of air and water from the radiator comprises a vertically disposed tube 30 which is provided in its lower end with a valve chamber 31 and with a discharge chamber 32 in its upper end, and these two chambers are separated by a contraction in the wall of tube 30 which forms a valve seat 33 for the valve 34. A cap 35 closes the lower end of I chamber 31 and this cap is further provided with exterior threads 36 which engage corresponding threads in the lower end of a hollow cylinder 37 into which tube 30 projects. Valve 34 is actuated toward and away from its seat 33 through the medium of a valve-stem 39 by means of a hollow inclosed float 40 which is arranged above tube 30 within cylinder 37. In the initial operation of the device with the water level within cylinder 37 and water receiving pan 22 standing below float 40 valve 34 Wlll be occupying an unseated position, thereby allowing the water discharging through pipes 20, 27 and 42 to freely move upward in chamber 31 and pass valve 34, and into discharge chamber 32, from whence it is discharged into pan 22 through plpe 42. Cylinder 37 is provided near its lower end with a number of apertures 24 which communicate with the interior of pan 22 so that a uniform water level can be maintained in both said cylinder and pan. Pipe 42, through which air and water is discharged into pan 22, extends downward and terminates below the lower edges of apertures 24 in cylinder 37 and near the bottom of pan 22, in order to keep the discharge end of pipe 42 constantly sealed and thereby eliminate the noise that usually accompanies the exhausting of the air from steam and hot water radiators. After suflicient water has been discharged into pan 22 to raise the water level in cylinder 37 to such a height as to elevate float 40, valve 34 will be seated and further discharge of water prevented. 'As the water pan 22 is situated in close proximity to the radiator and is subjected to the heat radiated therefrom, the action of converting water into vapor is accelerated. This arrangement will insure that the air within the room will be constantly charged with the desired amount of moisture. When the action of evaporation has reduced the volume of water and reduced its level to no longer sustain float 40 the latter will descend causing valve 34 to be unseated and allowing a further supply of water to be discharged into pan 22 until the water level therein has again been raised to a point to elevate float 40, thus again reseating valve 34 and shutting off the further discharge of water.

With the above construction in mind, it

will be noted that the air from the radiator can be silently exhausted, together with a supply of water for humidifying the atmosphere of the room; while the volume of water consumed for humidifying purposes can be automatically replaced, and the movements of the air and water exhausted can be positively controlled.

Having thus fully described my said invention, what I desire to secure by Letters Patent, is

1. In combination, with a steam and hot water radiator, a pan for receiving the air and Water discharged from said .radiator, an air and water conductor-means communicating with the interior of the radiator and discharging into said pan, a valve holding tube interposed in said conductor-means, a valve arranged within said tube for controlling the flow of air and water toward the pan, means actuated by the rise and fall of the water level within said pan for operating said valve, and a discharge pipe communicating with the hollow tube above the valve and having its discharge end terminating within and below a determined minimum water level within said pan.

In combination, with a steam and hot water radiator, a pan for receiving the air and water discharged from said radiator, an air and water conductor-means communicating with the interior of the radiator and discharging into said pan, coils in said air and water conductor-means for converting the incoming steam into water, a valve holding tube interposed in said conductor-means, a valve arranged within said tube for controlling the flow of air and water toward u the pan, means actuated by the rise and fall of the water level within said pan for operating said valve, and a discharge pipe communicating with the hollow tube above the valve and having its discharge end telminating within and below a determined minimum water level within said pan.
